Intel 2-port 10 Gb Ethernet Expansion Card (CFFh) for
IBM BladeCenter
IBM Redbooks Product Guide
The Intel 2-port 10 Gb Ethernet Expansion Card (CFFh) for IBM BladeCenter is a dual-port 10 Gb
Ethernet card that is powered by an Intel Ethernet 82599 third generation 10 Gb Ethernet Controller. This
card offers full line-rate 10 Gbps performance for high-IO intensive clients, and showcases the next
generation in 10 GbE networking features for the enterprise network and data center.
Data Center and Large Enterprise customers demand reliable performance from their networking
equipment to ensure quick and easy deployment and provisioning of new systems, provide uninterrupted
application services across their network to their users, and require maximum network performance for
those applications. In addition, this adapter supports the latest virtualization technology, Intel
Virtualization Technology for Connectivity (Intel VT for Connectivity).
Figure 1 shows the Intel 2-port 10 Gb Ethernet Expansion Card (CFFh).

Did you know?
Intel VT for Connectivity is a suite of hardware assists that improves overall system performance by
lowering the I/O impact in a virtualized environment. This improves CPU usage, reduces system latency,
and improves I/O throughput. Intel VT for Connectivity includes two major components: Virtual Machine
Device Queues (VMDq) and Intel I/O Acceleration Technology (Intel I/OAT).

Intel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration
across the platform, from networking devices to the chipset and processors, which helps to improve
system performance and application response times. The different features include Intel® QuickData,
Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others.
Virtual Machine Device Queues (VMDq) reduces I/O impact on the hypervisor in a virtualized server by
performing data sorting and coalescing in the network silicon. VMDq technology makes use of multiple
queues in the network controller. With VMDq, as data packets enter the network adapter, they are sorted,
and packets to the same destination (or virtual machine) are grouped together in a single queue. The
packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving
the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.
The expansion card has iSCSI support for proven native OS and VMM iSCSI initiators. Historically,
CRC32C computation has degraded system performance, but now with the CRC instruction set included
in the latest Intel Xeon processors, CRC validation is possible with minimal impact to network throughput
while delivering data integrity.

In BladeCenter H, the ports of CFFh cards are routed through the midplane to I/O bays 7, 8, 9, and 10, as
shown in Figure 3. The BladeCenter HT works in a similar way because the CFFh cards are also routed
through the midplane to I/O bays 7, 8, 9, and 10.

The Intel 2-port 10 Gb Ethernet Expansion Card (CFFh) requires that two I/O modules be installed in bays
7 and 9 of the BladeCenter H or HT chassis, as shown in Table 4.

Popular configurations
Figure 4 shows a configuration using the Intel 2-port 10 Gb Ethernet Expansion Card (CFFh) together
with two BNT Virtual Fabric 10 Gb Switch Modules. This solution enables two 10 Gbps Ethernet
connections from each blade server. Two BNT Virtual Fabric 10 Gb Switch Modules are installed in bay 7
and bay 9 of the BladeCenter H chassis. All connections between the controller, card, and the switch
modules are internal to the chassis. No internal cabling is needed.
